Quoted from The_Director:That’s what I would have imagined, but these, the first ball sits past. They are a complete mess I think, but somehow were working for awhile. That’s why I just now took a look. Anyone with some picks, I’d really appreciate it. I’m not even sure the right switches are being used…
Those Data East switches are junk. You should replace it with the opto board from @Davi, I enclosed pics of this board with correct wiring sequence. This is from GNR, but Simpson should be the same. Davi has a list going now for another run of these boards. J
